London Area Code: 020

The telephone area code for the UK capital city of London is 020.

The vast majority of localities and boroughs in the UK & England capital city of London use the 020 telephone area code, therefore if you would like to call a person or business situated in the city then you should first dial 020 followed by the remaining eight digits of the phone number you wish to call. Similarly if you have recieved a call from a number starting with 020 then it almost certainly came from an address located in the city. Please note that some London boroughs, for example Bromley, Havering and Hillingdon, do not use the 020 area code.

Cost of calling 020 (London) phone numbers

Calls to all local geographic phone numbers in the UK (01 & 02 prefixed numbers) are charged at the exact same rate, therefore it will cost you the same calling a personal landline in London as it will making the equivalent call to Manchester. The rate depends on what time & day you make the call on and a standard call access fee that is determined by your landline provider is also applied to the call. Calling a person or business in London from a mobile will be free if you use your free inclusive minutes on your tariff or monthly contract in order to make the call, however please check with your mobile network provider for full details on call charges.

Calling London from overseas

Calling a London telephone number from overseas is a simple process which is easy for you to follow. You should remove the first zero ‘0’ from the 020 area code and then replace it with the international dialling code for the United Kingdom, which is +44. This gives you a new ‘international calling code’ for London: +44 20. Therefore if you wanted to call the Tower of London on their visitor information phone number 020 3166 6000 from overseas you should instead dial +44 20 3166 6000.

Phone numbers for popular London attractions

Phone numbers which start with the 020 prefix are well received throughout the UK and are particularly favourable for residents living in the city in comparison to national phone numbers such as 03 and 08 numbers. This is because 020 numbers are registered by default to London addresses, whereas non-geographic national numbers are not as traceable to a specific location and are therefore more likely to be used by unscrupulous telesales companies which use cold-calling tactics.
